Richard Allen (University of Hawaii) (2011) CIL:36260, Vorticella convallaria, cell by organism, eukaryotic cell, Eukaryotic Protist, Ciliated Protist. CIL. Dataset

Like other ciliates two types of nuclei are present. A germinative micronucleus and a RNA-producing macronucleus. Both have nuclear envelopes with pores and both have ribosomes attached to their outer membranes. Heterochromatin bodies are the only prominently stained entities in the micronucleus. A few microtubules are also present. TEM taken on 3/29/71 by R. Allen with Hitachi HU11A operating at 75kV. Mag. 13,750X. Bar = 0.5µm. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. There is a high resolution version of this image in the library (CIL:39452) which is available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).

与其他纤毛虫类似，该数据集中存在两种类型的细胞核：生殖性微核和RNA产生性大核。两者均具有带有孔隙的核膜，且其外膜均附着有核糖体。异染色质体是微核中唯一显著染色的实体。此外，还存在少量微管。该透射电子显微镜（TEM）图像由R. Allen于1971年3月29日使用日立HU11A透射电子显微镜拍摄，工作电压为75kV。放大倍数为13,750倍，标尺长度为0.5微米。负片印制在纸上，图像随后被扫描至Photoshop中。此数字化图像可供进行定性分析。图书馆中存有该图像的高分辨率版本（CIL:39452），可供进行定量分析。更多详细信息请访问（http://www5.pbrc.hawaii.edu/allen/）。
